Step-by-step explanation:

Answer: The GCF of 60, 70, and 80 is 10.

Step-by-step explanation: If you think about it, the GCF is definitaly going to be 10. That is because you can multiply 10 to get 60, 70, and 80. There is no other number higher than 10 that can be multiplied by something to get all of these values.

Answer:

A' (-0.20, -0.75)

B' (-1.50, -1.50)

C' (-1.79, -0.29)

D' (-10.45, -0.20)

Step-by-step explanation:

you just need to multiply all the points by -0.5, sorry not sure how to verify the ratios for the sidelength tho

The coordinates of the dilated quadrilateral are A'(-0.2, -0.75), B'(-1.5, -1.5), C'(-1.79, -0.285) and D'(-1.045, -0.2) and the ratio of each side length of A'B'C'D' to the corresponding side length of ABCD is equal to the dilation factor.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

We need to Dilate quadrilateral ABCD again with the origin as the center of dilation and a scale factor of -0.5.

The side lengths of the corresponding sides in each quadrilateral.

A(0.4, 1.5)

B(3, 3)

C(3.58, 0.57)

D(2.09, 0.4)

The scale factor is -0.5.

Now A'=(-0.4×0.5, -1.5×0.5)

=(-0.2, -0.75)

B'=(3×-0.5, 3×-0.5)

=(-1.5, -1.5)

C'=(3.58×-0.5, 0.57×0.5)

C'=(-1.79, -0.285)

D'=(2.09×-0.5, 0.4×-0.5)

D'=(-1.045, -0.2)

Hence, the coordinates of the dilated quadrilateral are A'(-0.2, -0.75), B'(-1.5, -1.5), C'(-1.79, -0.285) and D'(-1.045, -0.2) and the ratio of each side length of A'B'C'D' to the corresponding side length of ABCD is equal to the dilation factor.

Answer:

La variación de calor por unidad de tiempo es 4285.714 watts, es decir, joules por segundo.

Step-by-step explanation:

Asumamos que la transferencia de calor es enteramente por conducción, en estado estable y unidimensional´y que la ventana es representada por una placa plana. Bajo estas consideraciones, la ecuación de conducción es la siguiente:

[tex]\dot Q = \frac{k\cdot w\cdot h}{l}\cdot (T_{i}-T_{o})[/tex] (1)

Donde:

[tex]\dot Q[/tex] - Tasa de transferencia de calor, medida en watts.

[tex]k[/tex] - Conductividad térmica, medida en watts por metro-grado Celsius.

[tex]w[/tex] - Ancho de la ventana de vidrio, medido en metros.

[tex]h[/tex] - Altura de la ventana de vidrio, medida en metros.

[tex]l[/tex] - Espesor de la ventana de vidrio, medida en metros.

[tex]T_{i}[/tex] - Temperatura interior del vidrio, medida en grados Celsius.

[tex]T_{o}[/tex] - Temperatura exterior del vidrio, medida en grados Celsius.

Si conocemos que [tex]k = 0.8\,\frac{W}{m\cdot ^{\circ}C}[/tex], [tex]w = 2.5\,m[/tex], [tex]h = 1.5\,m[/tex], [tex]l = 2.8\times 10^{-3}\,m[/tex], [tex]T_{o} = 16\,^{\circ}C[/tex] y [tex]T_{i} = 20\,^{\circ}C[/tex], entonces la tasa de transferencia de calor es:

[tex]\dot Q = \left[\frac{\left(0.8\,\frac{W}{m\cdot ^{\circ}C} \right)\cdot (2.5\,m)\cdot (1.5\,m)}{2.8\times 10^{-3}\,m} \right]\cdot (20\,^{\circ}C-16\,^{\circ}C)[/tex]

[tex]\dot Q = 4285.714\,W[/tex]

La variación de calor por unidad de tiempo es 4285.714 watts, es decir, joules por segundo.

Answer:

Creo que es b

Step-by-step explanation:

The linear function that passes through the point (3,6) is given by: Option C: [tex]y = 2x[/tex]

All the points (and only those points) which lie on the graph of the function satisfy its equation.

Thus, if a point lies on the graph of a function, then it must also satisfy the function.

Checking all the options to see if (3,6) lies on them:

Usually points are of the form (x,y). Thus, we have: (x,y) = (3,6) means x = 3, and y = 6.

Putting these values in the equation, we get:

[tex]y = 3x + 6\\6 = 3(3) + 6\\6 = 9 + 6\\6 = 15[/tex]

This is wrong. Thus, the point (3,6) doesn't satisfy this equation, and therefore, doesn't lie on its graph.

Putting x = 3, y = 6 in this equation, we get:

[tex]y = 6x - 3\\6 = 6(3) - 3\\6 = 18 - 3 \\6 = 12[/tex]

This is wrong. Thus, the point (3,6) doesn't satisfy this equation, and therefore, doesn't lie on its graph.

Putting x = 3, y = 6 in this equation, we get:

[tex]y = 2x\\6 = 3(2)\\6 = 6[/tex]

This is correct. Thus, the point (3,6) satisfy this equation, and therefore, lies on its graph.

Thus, the linear function that passes through the point (3,6) is given by: Option C: [tex]y = 2x[/tex]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the function

[tex]y=3x+7[/tex]

As we know that  the slope-intercept of the line equation is

[tex]y = mx+b[/tex]

where m is the slope and b is the y-intercept

so comparing the equation [tex]y=3x+7[/tex] with the slope-intercept of the line equation, we conclude that

[tex]y = 3x+7[/tex]

[tex]m = 3[/tex]

So, the slope of the line is [tex]m = 3[/tex]

As the function is

[tex]y = 3x+7[/tex]

Now, if we double the slope,

The slope will become: 2m = 2(3) = 6

Therefore, the function of the graph after doubling the slope will become:

[tex]y = 6x+7[/tex]

Answer:

m∠8 = 30°

Step-by-step explanation:

Since line AB is parallel to line CD, and m∠4 = 30°, therefore:

m∠4 and m∠8 are corresponding angles.corewslinding angles are congruent.

Therefore, this means that their measure would be equal to each other, since they are congruent.

Thus:

m∠8 = 30°

Answer: 30°

Step-by-step explanation:

Answer:

100

Step-by-step explanation:

The angles are on the same side of the transversal.  They are corresponding angles, so they are equal. Put algebraically

4a = 2a + 50                Subtract 2a from both sides.

4a-2a = 2a-2a + 50     Combine

2a = 50                        Divide by 2

2a/2 = 50/2

a = 25

<VYX = 4*a = 4*25 = 100
